Both parts carry ROHS3 compliance and equivalent moisture sensitivity ratings, ensuring regulatory and environmental consistency in applications. The YC164-JR-07820RL is qualified for automotive AEC-Q200 applications, DDRAM, and SDRAM environments.

Frequently Asked Questions (FAQ)

Q: Can the YC164-JR-07820RL replace the MNR14ERAPJ821 in existing designs?

A: Yes. Both components share identical electrical parameters (820 Ohm, ±5% tolerance, 62.5mW per element, ±200ppm/°C), circuit configuration (isolated 4-resistor array), and mechanical specifications (1206 package, 8-pin surface mount). Pin-to-pin compatibility is established.

Q: Are there packaging differences between these parts?

A: The MNR14ERAPJ821 is supplied in Cut Tape (CT) & Digi-Reel format, while the YC164-JR-07820RL is supplied in Tape & Reel (TR). Both use identical 1206 (3216 Metric) packages with convex, long side terminals. The height difference (0.024" vs 0.028" seated maximum) falls within standard PCB assembly tolerances for surface mount components.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. Moisture sensitivity level is 1 (unlimited) for both parts.

Q: Is the YC164-JR-07820RL suitable for automotive applications?

A: The YC164-JR-07820RL carries AEC-Q200 automotive qualification. Confirm application-specific requirements with your design team.
